Re : Decommissioned node appears in logs, and is sometimes marked as
"UNREACHEABLE" in `nodetool describecluster`
hi;
we decommissioned nodes in a datacenter a while back. Those nodes keep
showing up in the logs, and also sometimes marked as UNREACHABLE when
`nodetool describecluster` is run.
However these nodes do not show up in `nodetool status` and
`nodetool ring`.
Below are a couple lines from the logs.
2015-08-27 04:38:16,180 [GossipStage:473] INFO Gossiper InetAddress /
10.0.0.1 is now DOWN
2015-08-27 04:38:16,183 [GossipStage:473] INFO StorageService Removing
tokens [85070591730234615865843651857942052865] for /10.0.0.1
thanks

Are they in the system.peers table?

What version of Cassandra?
This happens a lot in 1.0-2.0.

Do they show up in nodetool gossipinfo?
Either way, you probably need to invoke Gossiper.unsafeAssassinateEndpoints
via JMX as described in step 1 here:
